where X and Y are topological spaces, and [0,1] is the unit interval. This map F is called a homotopy between two maps f and g, where f(x) = F(x,0) and g(x) = F(x,1).

In Switzer's text, homology is introduced through the concept of chain complexes. A chain complex is a sequence of abelian groups and homomorphisms: switzer algebraic topology homotopy and homology pdf

F: X × [0,1] → Y

Algebraic topology is a branch of mathematics that studies the properties of topological spaces using algebraic tools. Two fundamental concepts in algebraic topology are homotopy and homology, which help us understand the structure and properties of topological spaces. In this blog post, we will explore these concepts through the lens of Norman Switzer's classic text, "Algebraic Topology - Homotopy and Homology". where X and Y are topological spaces, and
